-EL'ECTRO-TH ERAPEU TI CAL CHAIR.

SPECIFICATION forming part of Letters Patent Ito-238,721, dated MarchApplication filed November 13, 1880. (No model.)

clear, and exact description of the constructipnfand operation of thesame, reference being had to the annexed drawing, making'a part of thisspecification, and to the letters and figures of reference markedthereon.

The figure of the drawing is a' perspective view'of my device.

This invention relates to the application of electricity in the cure ofdiseases. The invention consists in a chair of pecul-iar constructionwith appliances whereby the treatment may be general or'local, asdesired.

In the annexed drawings, Ais a chair, having arms B B, back 0, hinged toseat D and made adjustable by pins, and notched arms, and foot-rest E,hinged to the seat D by sup ports F F, and made adjustable by rod '0,and notched arms d. There is a drawer beneath the chair, and a hingedsupport behind.

Supported at one side of the chair is an index-board, I, having thereonthe bindingscrews K, of any desired number.

L represents wiresleading from an adja cent battery to the screws K, andadapted to be fastened to the latter at the top. Leading from the bottomof these screws Kare wires M, which terminate in plates arranged upon difi'erent parts of the chair. Attached to the chair-frame are thesevarious plates, each being shaped and adapted to fit different portionsof the human form.

N is a rod sliding in brackets e, and held by set-screws, said rodcarrying a plate, 0,

made to fit the head andshoulders, and a" plate, P, to fit the back,both plates being adjustable by set-screws along the rod N.

.Upon the arms of the chair are arranged plates Q and R, to fit the armsand hands,

.vso

and on the inside of said armsare plates S, to fit the hips, all-threebeing adjustable.

T is an elastic band carrying a plate, V, to fit the stomach.

U is a plate on the seat of the chair. W.

may be constructed to fit any portions of the form, those mentionedbeing the ones most commonly tobe used.

In using this devicethe patient is placed in the chair, which, by itsadjustable back and foot-support, is put into an easy and comfortableposition.

In treating diseases the great point is to readily infect the part whichis the location of the trouble. It is the prime object of this inventionto furnish a device by which such treatment can be localized, and onlythose parts of the body which are diseased subjected to the action ofthe electricity directly, leaving the other portions untouched and onlyaffected indirectly. i

The patient being seated, as described, the proper plate for the part tobe treated is put in place. Now, by connecting its bindingscrew with thebattery,a-current of electricity will flow directly to the desired part.More than one part'can be treated at the same time, and by sending thecurrent direct it can be better manipulated, and the required'amountbetter determined, than if it were conveyed at one point of. the bodyfor all diseased portions.

Iii-using this chair it is of course understood that the same isinsulated, and that the plate and wire through which the current isadministered is an anode, and the patient is connected by a cathode withthe battery. v

I am aware that electro-medica-l and electro-galvanic chairs are notnew, and I do not,

broadly, claim the same. WhatI claim is- In a magnetic chair, the hingedback 0,

der plate 0, and the adjustable'back-plate P,

both secured to the rod N, workingiu brack- 'provided with theadjustable head and shouletse, the seat D, having plate U, the arms B,

having arm and hand plates Q and, R, the
